The Stacked Spline Area 100% chart is a variation of the Spline Area chart. The areas are stacked so that each series adjoins but does not overlap the preceding series. This chart displays contributions for each data point to the category as a percentage.

To create a vertical Stacked Spline Area Chart 100% chart, set the SeriesOrientation property to Vertical. Set the RadChart DefaultType property or ChartSeries.Type to StackedSplineArea100.

To create a horizontal Stacked Spline Area Chart 100% chart, set the SeriesOrientation property to Horizontal. Set the RadChart DefaultType property or ChartSeries.Type to StackedSplineArea100.

To display the label values as percentages, change the DefaultLabelValue for each chart series from "#Y" (the numeric value for each data point) to "#%" (the percentage of each data point to the category).
